如何让XMLSerializer将名称空间添加到嵌套对象中的属性？

Question

这是我得到：

<ex:test soap:mustUnderstand="1" xmlns:ex="http://www.example.com/namespace"> 
    <ex:A Type="lorem">ipsum</ex:A> 
</ex:test> 

这就是我想要的：（注意类型属性的前缀是前）

<ex:test soap:mustUnderstand="1" xmlns:ex="http://www.example.com/namespace"> 
    <ex:A ex:Type="lorem">ipsum</ex:A> 
</ex:test> 

这是我的代码：

[XmlType(Namespace = "http://www.example.com/namespace")] 
    [XmlRoot("ex", Namespace = "http://www.example.com/namespace")] 
    public class TestSoapHeader : SoapHeader { 
    private TestSoapHeaderTypeValuePair _a; 

    public TestHeader() { 
     MustUnderstand = true; 
    } 

    [XmlNamespaceDeclarations] 
    public XmlSerializerNamespaces xmlsn { 
     get { 
     XmlSerializerNamespaces xsn = new XmlSerializerNamespaces(); 
     xsn.Add("ex", "http://www.example.com/namespace"); 
     return xsn; 
     } 
     set { } 
    } 

    public TestSoapHeaderTypeValuePair A { 
     get { return _a; } 
     set { _a = value; } 
    } 

    } 

    [XmlType(Namespace = "http://www.example.com/namespace")] 
    public class TestSoapHeaderTypeValuePair { 
    private string _type; 
    private string _value; 

    [XmlNamespaceDeclarations] 
    public XmlSerializerNamespaces xmlsn 
    { 
     get 
     { 
     XmlSerializerNamespaces xsn = new XmlSerializerNamespaces(); 
     xsn.Add("ex", "http://www.example.com/namespace"); 
     return xsn; 
     } 
     set { } 
    } 

    public TestSoapHeaderTypeValuePair(string type, string value) { 
     Type = type; 
     Value = value; 
    } 

    public TestSoapHeaderTypeValuePair() {} 

    [System.Xml.Serialization.XmlAttributeAttribute("type", Namespace = "http://www.example.com/namespace")] 
    public string Type { 
     get { return _type; } 
     set { _type = value; } 
    } 

    [System.Xml.Serialization.XmlText()] 
    public string Value { 
     get { return _value; } 
     set { _value = value; } 
    } 
    }

IXmlSerializable也许？

注意我还添加了（到A）：

[XmlElement("A", Namespace = "http://www.example.com/namespace")] 
public TestSoapHeaderTypeValuePair A {...} 

下面的代码：

public class TestSoapHeaderTypeValuePair : IXmlSerializable 
{ 
    private string _type; 
    private string _value; 

    public TestSoapHeaderTypeValuePair(string type, string value) 
    { 
     Type = type; 
     Value = value; 
    } 

    public TestSoapHeaderTypeValuePair() { } 

    public string Type 
    { 
     get { return _type; } 
     set { _type = value; } 
    } 

    public string Value 
    { 
     get { return _value; } 
     set { _value = value; } 
    } 

    #region IXmlSerializable Members 

    System.Xml.Schema.XmlSchema IXmlSerializable.GetSchema() 
    { 
     return null; 
    } 

    void IXmlSerializable.ReadXml(System.Xml.XmlReader reader) 
    { 
     throw new NotImplementedException(); 
    } 

    void IXmlSerializable.WriteXml(System.Xml.XmlWriter writer) 
    { 
     writer.WriteAttributeString("ex", "type", "http://www.example.com/namespace", Type); 
     writer.WriteString(Value); 
    } 

    #endregion 
}

例如XSD.EXE complex.xml XSD.EXE gen1.xsd gen2.xsd/C

无需触摸XSD生成的文件（除了更换[] [] - > []）

XmlSerializerNamespaces ns = new XmlSerializerNamespaces(); 
ns.Add("dfs", "http://schemas.microsoft.com/office/infopath/2003/dataFormSolution"); 
ns.Add("d", "http://schemas.microsoft.com/office/infopath/2009/WSSList/dataFields"); 
ns.Add("pc", "http://schemas.microsoft.com/office/infopath/2007/PartnerControls"); 

XmlSerializer serializer = new XmlSerializer(typeof(myFields)); 
StringBuilder sb = new StringBuilder(); 

using (StringWriter writer = new StringWriter(sb)) 
{ 
    serializer.Serialize(writer, myFields, ns); 

    return sb.ToString(); 
}
